CefShutdown Method

Shuts down CefSharp and the underlying CEF infrastructure. This method is safe to call multiple times; it will only shut down CEF on the first call (all subsequent calls will be ignored). This method should be called on the main application thread to shut down the CEF browser process before the application exits. If you are Using CefSharp.OffScreen then you must call this explicitly before your application exits or it will hang. This method must be called on the same thread as Initialize. If you don't call Shutdown explicitly then CefSharp.Wpf and CefSharp.WinForms versions will do their best to call Shutdown for you, if your application is having trouble closing then call thus explicitly.
